l Claim. (Cl. 302-25) This invention relates to means for handling and transporting pulverulent material, such as flour, pulverized coal and cement, granular material, such as rye, wheat, oats, corn and flaxseed, and other material, such as slimes or slurries and concrete. Said means include a pressure container for the material through It has been found that it is only possible to transport said material discharged from the container and the discharge outlet for a distance not greater than 150 feet.

It is the object of the invention to provide use for the material of motors, screw conveyers or transport conduit.

This means comprise a. conical casing having Without the aid boosters in the for the container.

Other objects and advantages of the invention will be disclosed in the following description of the invention.

In the drawings accompanying and forming a part of this application,

Figure 1 is a sectional view of the bottom por- Figure 4 is a partial view looking at the larger end of the conical casing.

Figure 5 is an elevational View of a pressure container connected in communication with a depository for the material discharged from the container and showing the embodiment of the invention incorporated in said connection.

The invention is shown in the accompanying drawings in combination with a pressure container 5 having a material ller opening at the upper portion adapted to be pneumatically sealed by a closure, as indicated at 'I in Figure 5, and a hopper bottom, as shown at 8 in Figure l. The hopper bottom is arranged with a material discharge member consisting of a cup member secured to said bottom and having a discharge conduit In connected at one end in Fluid pressure, such as compressed air or steam, is delivered from a suitable source of supply, not shown, to the top and hopper bottom of the container to agitate and discharge the material from the container through the discharge conduit. The iiuid pressure is delivered from the source of supply through a conduit, partly shown at i4 in Figure l, con nected at one end to the source of supply and nected to a pipe portion I6 mounted on the base I3, as shown at l1 in Figure 1. The pipe gportion I6 is provided with a shut-01T valve shown terial toward the hopper bottom 8 and discharge conduit I0. The lateral pipe extension |91 is also connected in communication with a series of nozzles 22 mounted in the hopper bottom 8 to spray ud pressure into the hopper bottom to aerate and wash the material from the Wall of the hopper bottom. The lateral pipe extension I9 is further connected in communication with a series of nozzles 23 mounted in the cup member 9 to spray fluid pressure into said cup member andl further agitate the material in the cup member. The material in the cup member is forced'into the discharge conduit 1li by the fluid pressure from the pipe extension |9 by connecting said pipe extension in communication with a nozzle 24 mounted in the cup member 9 in line with the outlet thereof, as shown in Figure l.

The material discharge conduit lil is connected in communication with a place of use or a depository for said material and shown in Figure to be a storage bin 25 connected in communication with the free end of the discharge conduit lll through a transport conduit 2t.

It has been found that the fluid pressure delivered to the container 6 from the pipe eXtensioni|9"was only' able to transport the discharged material for a maximum distance of l5() feet from the container.

Means have been provided to increase this distance in which the material is transported from the container 6 to the bin 25 without the use of additional means of propulsion than that provided by the fluid pressure delivered to the container by the conduit |4. Said means comprises a conical casing 21 having a diameter at the smaller end substantially equal to the diameter of the conduits |3 and 2E. The larger end of said casing is provided with an annular series of nozzles 28 spaced equidistances apart in anannular plate 29 secured tothe larger end of the conical casing 21 as by welding 3i! and having an opening 3| corresponding to the diameter of the smaller end of the conical casing, as shown in Figure 3. The nozzles 23 are secured in equidistantly spaced holes 32 in the plate by welding 33 with the nozzles extending at an angle diverging from the side wall of the casing 221, so that the nozzles will eject streams of fluid pressure in paths converging at a point beyond the smaller end of the conical casing 21 and substantially in the center of the stream of travel of flow of the material in fluid suspension in the conduits Il) and 25. The nozzles 23 communicate with an annular groove 34 in the outer face of the plate 23 and communicating with r the holes 32. The fluid pressure is supplied to the nozzles 28 and annular groove 34 from the supply conduit i4 through a hose 35 connected at one end in communication with a coupling member. mounted in communication with the pipe portion |5 and arranged with a Valve mechanism and a check valve, as indicated in a general way at 36 and 31, respectively, to shut-off and control the flow of fluid pressure from the source of Vsupply to the nozzles 28. The opposite end of the hose 35 is connected in communication with a coupling member 3|! mounted on a nipple 35 secured by' welding '4D to an annular plate 4| having an opening 42 therethrough communicating with the nipple 33 and the annular groove. 34, as shown in Figure 3. The annular plate 4| is secured by welding 43 to a tubular member 44 having a flange at the opposite end in the `form of an annular plate 45 secured to said end of the tubular member 44 by welding 46. The tubular member 44 and annular plates 4|, 45 form a coupling member 44- having flanges 4|, 45fat-the opposite ends. Said coupling-member is-secured to the conical casing 21 with the opening 42- in register with forced in the same manner as :,terial, is

thereof on a leg portion of an a portion of the groove 34 and the remaining portion of said groove closed by the ilange 4|. This is accomplished by bolts 59 engaged in equidistantly spaced holes in the ange 4| and screw threaded in corresponding holes 60 in the annular plate 29.

The larger end of the conical casing 21 is removably connected to the free end of the discharge conduit |0 by the coupling member 44 having the flange secured to a ange on the free end of the discharge conduit ||l in the form of an annular plate 41 screw threaded on the discharge conduit I3, as shown in Figure 3. Bolts 48 are secured in alined openings in the flanges 45 and 41 with the openings in the flange 45- reinforced by washers 49 welded thereto.

The smaller end of the conical casing 21 is adapted to be connected in communication with the transport conduit 25 by providing a flange on said smaller end in the form of a flat ring 52 engaged on a straight wall end portion 5| at the smaller end of the conical casing and the flange secured to the casing by welding 52. rThe ring flange 5|) is arranged with holes reinthe openings in flange 45, as shown at 53. The flange is removably connected to a flange 54, in the form of a plate screw threaded on one end of a straight wall coupling member 55, by bolts engaged and secured in corresponding holes in the flanges 53 and 54, as shown at 56 in Figure 3. The trans-- port conduit 25, which is usually of flexible maslidably engaged on the free end of the coupling member 55 as shown in Figures l and 3.

To facilitate mounting and removal of the conical casing relative to the discharge conduit lll, said casing is provided with a handle in the form of a bar 51 mounted midway of the ends angle bracket 58 secured at the other leg portion on the outer face of the flange 50, as shown in Figure 2..

ln the operation ci the device, the valves i8 and 36 are actuated to open position when it is desired to discharge material from the container, and which will cause a series of converging jets of fluid pressure from the nozzles 23 gradually intermingling with the dow of the fluid suspended material and greatly increasing the buoyancy of said material.

Having thus described my invention, I claim:

In means 'for handling and transporting pnlverulent, granular and the like material, a conduit for transporting such material in fluid suspension, a conical casing interposed in the conduit, and annular series of spaced nozzles mounted in the larger end of the casing and connected to a source of fluid pressure to direct an annular stream of fiuid pressure about the flow of duid suspended material in the conduit, and means to connect the larger end of the casing to a section of the conduit and mount the nozzles in the larger end of the casing comprising an annular plate having an annular groove in one face thereof and a series of holes communicating with the annular groove and opening to the other face of the plate for mounth ing the nozzles in said plate in communication with the annular groove and said plate secured to the larger end of the casing, and a second annular plate secured to the facel of the rst annular plate arranged with the annular groove to close said groove and havingan opening there through communicating with the annular groove and arranged to be connected to the source of uid pressure and said second plate secured to the conduit section.
